In vitro

AG-490 inhibits HER-2 driven cell proliferation with IC50 of 3.5 μM. [1] Corresponding to the specific dose-dependent inhibition of constitutively activated JAK2 in pre-B acute leukemia (ALL) cells, AG-490 (5 μM) almost completely blocks the growth of all ALL cells by inducing programmed cell death, with no deleterious effect on normal hematopoiesis. AG-490 does not inhibit the activities of Lck, Lyn, Btk, Syk, and Src. [2] AG-490 (60-100 μM) blocks the constitutive activation of Stat3sm, and inhibits spontaneous as well as interleukin 2-induced growth of mycosis fungoides (MF) tumor cells with IC50 values of 75 μM and 20 μM, respectively. [3] AG-490 potently inhibits IL-2-mediated human T cell growth with an IC50 of 25 μM by blocking the activities of JAK3 and STAT5a/b. [4] Although AG-490 alone has no effect on proliferation of FDrv210H cells at a concentration of 5 μM, AG-490 can synergize with STI571 to enhance its inhibitory effect on p210bcr-abl driven proliferation. [5] AG-490 significantly inhibits the constitutive activation of Stat3 in MOPC, MPC11, and S194 cells, leading to dramatic dose-dependent apoptosis. [6] AG-490 (100 μM) inhibits Akt phosphorylation, inhibits the activation of nuclear factor-κB, and causes the activation of GSK-3β, leading to the reduction of c-Myc. AG-490 (50 μM) can induce apoptosis of imatinib-resistant BaF3 cells expressing T315I and E255K mutants of Bcr-Abl. [7] AG-490 at 30 μM inhibits not only Epo-induced phosphorylation of wild-type JAK2 but also constitutive phosphorylation of the JAK2 V617F mutant. AG-490 also potently inhibits cytokine-independent cell growth induced by the JAK2 V617F mutant in BaF3 cells. [8]

In vivo Administration of AG-490 drastically reduces the numbers of CD45+ and HLA-DR+ cells from 48 % and 46% in bone marrow of untreated mice, as well as 38% and 22% in the spleen of untreated mice to undetectale levels. [2] In vivo administration of AG-490 causes murine myeloma tumor cell apoptosis but does not inhibit IL-12-mediated macrophage activation and IFN-γ production by lymphocytes. [6] Consistent with the in vitro blocking of JAK2 V617F mutant activity, AG-490 treatment at 0.5 mg/day for 10 days effectively inhibits JAK2 V617F mutant-induced tumorigenesis and tumor cell invasion in nude mice. [8] Combined therapy with AG-490 and IL-12 induces greater antitumor effects than either agent alone in a murine myeloma tumor model. [6]
